Abstract

DISPOSITIVO PARA LA TRANSMISION DE UNA SEÑAL DE TEMPERATURA POR MEDIOS MECANICOS, QUE CONSISTE EN LA UTILIZACION DE UN ELEMENTO TERMOSTATICO DE MATERIAL DILATABLE (1) QUE CUANDO EL COJINETE INTERIOR SE CALIENTA, EMPUJA SOBRE UNA VARILLA (2) SOLIDARIA CON LA PIEZA PORTADISCOS (3) Y A LA VEZ CON EL DISCO (4), EL CUAL SI LA TEMPERATURA ES SUFICIENTEMENTE ALTA, SE DESPLAZA HASTA TOMAR CONTACTO CON LA TAPA EXTERIOR DEL COJINETE MONTADO AL OTRO LADO DE LA RUEDA, ES DECIR EXTERIORMENTE, Y CUANTO MAS ELEVADA SEA LA TEMPERATURA ALCANZADA POR EL RODAMIENTO INTERIOR, MAYOR SERA LA PRESION EJERCIDA POR EL DISCO SOBRE LA TAPA Y MAS RAPIDAMENTE SE INCREMENTARA LA TEMPERATURA UMBRAL DE DETECCION, QUE SERA CAPTADA POR EL DISPOSITIVO DE CAPTACION SITUADO EN LA VIA.
